FIELD: chemistry.
SUBSTANCE: composition contains the following in pts. wt: 100 - triglyceride 12-hydroxy-cis-9 octadecenic acid (technical product of castor oil), 38.0-30.0 - toluene diisocyanate isomers, 2.7-30.0 - diethyleneglycol urethane and 0.1-1.0 - product of co-hydrolysis of methyltrichlorosilane with dimethyldichlorosilane. The sealant made from the proposed composition has low acoustic impedance.
EFFECT: improved electrophysical properties of sensors, resistance of hydroacoustic sensors sealed with the said sealant to effect of hydrostatic pressure of 10 MPa, which enables use of the sensors at up to 1000 m under water.
